Finally have given up

Alexis
I'm 19 with the logic of a 30 year old. 
I'm a licensed beautician in the state of Pennsylvania
Im the only one of my moms kids to graduate high school and further their education 
I just bought a brand new barely used 2013 Ford Focus 
And I'm really proud of myself 
I'm five months pregnant and my boyfriend is also 19 but 16 at heart... 
With bills being tight and my boyfriend having no bills except old fines which he makes payments on and a phone bill 
He called me tonight saying how he's gonna buy this and that for his xbox 
I love him very much but each time I say something about putting money away it's a fight 
I've finally given in and I'm just gonna get a second job and take matters into my own hands 
Has anyone worked two jobs in later pregnancy? And how did you do with it?
